Kohii is a calm, beautiful coffee journal app for people who care how their cup tastes. Open it to the coffee on your counter, brew it with a quiet timer, and keep every cup in your Journal — all on a warm, paper-like canvas inspired by the Japanese kissaten. Fully offline, no account. — A brew, start to finish — Whether you pull espresso, pour over a V60 or Chemex, press an AeroPress or French press, screw together a moka pot, or batch a cold brew, Kohii walks you through it. Set dose, yield, grind and temperature on a simple menu board — change the ratio and the water follows, a coffee ratio calculator built right into the recipe. Then brew with a timer that keeps the screen awake, and taste the cup while it's fresh. It's the espresso tracker and pour over coffee journal you've been keeping in a notebook — finally in one place. — Rate every cup — Give each brew an Overall rating on a tactile bean scale, and go deeper when a cup deserves it: Acidity, Bitterness, Sweetness and Body, plus a Tasting Notes page to write it down in your own words. Over time your coffee brew diary becomes a personal taste archive — you'll see exactly which beans and recipes you loved. — Your Journal — Every cup lands in the Journal, day by day, with The Counter and the stamps you've earned at the top. Open any brew as its own leaf — a card torn from the ledger, ready to share. — Track your beans — Build a shelf of every bag you buy. Save the roaster, origin, process, roast date, weight, and price, then watch a gentle freshness countdown tell you when each bag is at its peak. Every coffee has its own page — how fresh it is, how you usually rate it, and every brew you've made from it. This bean tracking app remembers what you bought, when you opened it, and how it brewed — so your next bag is a smarter choice. — Find your best brew — For every coffee, Kohii keeps your highest-rated cup as its Best Brew, with the full recipe saved. One tap on Brew Again starts a fresh brew with those exact settings, so a great cup is repeatable, not lucky. — Yours, and private — Kohii is fully offline. Your entire coffee journal lives in a local database on your device — nothing you log is uploaded, synced, or sold. Back up and restore your journal whenever you like, on your terms. — Simple, honest pricing — Kohii is free to use. Premium removes ads, lifts the shelf limit for unlimited bags, and opens dial-in traces and the full Counter. Choose a subscription, or a one-time purchase that's yours forever. Kohii is the barista log for home baristas, specialty coffee lovers, and anyone chasing a better cup — a quiet, well-made companion for the daily ritual of making coffee.
